They are well adapted for potato ject toprovide blades and shovels and rolling planting to cover the hills anddo as goody cutters ahead of the blades for use in the work as canbedone with hoes. These blades field where there are morning-glories orthe are crimped or curved at both edges and can like. be used on eitherside of the cultivator. 11 70 Other objects and advantages of theinvenare Shanks attached to the members 6 in any tion will hereinafterappear and the novel suitable manner and at their lower ends carryfeatures thereof will be particularly pointed shovels 15, as seenclearly in Figure 1.

Referring to the drawings, 10%, Thy flreb' 14 b d b th u l designatesthe axle, 2 the wheels, 3 the M 0 e eams 1S race y e members 19 at the'unction of which memdmft beam 4th@ Seat and 5 the Seat'support bers 14eandj 19 intelrmediate their ends are mg member all 0f WhlCh may be 0f myfeu provisions, as shown at 20, forthe attachknown 01" approved folm 0fCOIlStuftlOnment of other shovels, not shown, if desired. In fact, mylmprovement may be applled to When desired, other shovels may beattached practically any form of cultivator by removin the sockets 21,shown in Figure 2, but any Y ing the shovels and the like and applying.or all of these shovels may be omitted, as my improvement inlieuthereof. Such parts may be desired, such as are necessary only ofthe cultivator, therefore, as are well-known being employed. l

Angular braces 22, seen best in Figure 2, serve to strengthen and bracethe members 14 and 19.

The rolling cutters 13 may be of any Welllmown or approved form.

Parts of the cultivator herein shown and not described, such, forinstance, as thelevers 23 and their connections, may be of any wellknownform and Vmay be those of a cultivater of well-known construction towhich latter -the present improvements are applied.

In use, the blades elevate the dirt toward the corn, they leave no weedsin the corneld, the blades work ahead of the shovels as 15 will beevident, and one or two shovels may' be used to the frear of the bladesAor the shovels may be omitted entirely. The rolling cutters may beyoinitted under some circumstances, but are desirable vin cases wherethere are morning-glories or the like, but under other conditions theblades leave no weeds o r grass as they cut them, and the cutters may beused alone and the blades also work without the shovels.

In practice, the blades may be from say eight to twelve inches in width.One or two shove-ls may be used to the rear of the blades to loosen thedirt and a sniall cutter in front of the blades to cut morning-gloriesand the 3U like. The shovels will serve to loosen the dirt and theblades serve to elevate the dirt toward the corn or by reversal of theblades they will throw the dirt away from the corn.

h/Iodi'licaions in detail may be resorted to Vwithout departing tronithe spirit of the invention or sacrificing any of its advantages. l

-Whatis claimed as new is In a cultivator, a wheel supported-frame,

40 a seat-supporting member extending rearwardly therefrom, barsdepending from said member and carrying lo-ngitu-dinallyextendingrearwardly convergent bars and billing blades attached to saidlast-mentioned bars' in spaced parallel vert-ical relation, said bladesbeing crimped inwardly to provide a scraping edge. y

In testimony whereof I aliX my signature.
